jade遇到character "d" not allowed in prolog

Question

刚按照这个文章（prologhttp://www.tuicool.com/articles/rQjmIf）进行到三.3，命令行报错 ：
lee@lee-ThinkPad-E420:~$ jade jade.jade
jade:jade.jade:1:0:E: character "d" not allowed in prolog
jade:jade.jade:6:34:E: end of document in prolog
jade:E: cannot find "jade.dsl"; tried "jade.dsl", "/usr/local/share/sgml/jade.dsl", "/usr/share/sgml/jade.dsl"
jade:E: specification document does not have the DSSSL architecture as a base architecture

这是怎么回事？
